AP or FMJ vs. a tanks guns?

[Gryphon]

On the one hand, the tanks guns are clearly components that can be shot off. On the other hand, you get yellow sparks when you hit them (unlike the Hunter's guns!), indicating armor.

So which is it? Which ammo should I be using?

Tanks will take damage faster with FMJ ammo. Hunters will depend on the class of hunter and weapon used. For the most part. AP works best. But it also depends on how good of aim you have and if you know where to hit them.

[Crios1887]

Think of it this way. FMJ for impact damage, AP for putting holes in targets. FMJ tears stuff off a target, like weapons. AP blow holes through its face.

FMJ and soft point ammo do more damage to components while AP does more damage to armour. Tech view does not indicate the tank has armour on its guns, so FMJ and the like should be more effective.
This is pure speculation, but I think the guns have so much hit points that hits don't produce the 'critical component hit' sparks that you see when hitting the guns on a Hunter.
